This is a good time for "Yes... and no." It all depends on the type of organism.
In animals, which should be the both of us (If you are a human :) all cells are generally the same size. Of course, cells like nerve cells and muscle cells might not count in the reason that they can stretch to be relatively large or be the same size as other cells. For the most part, the same types of cells (i.e. bone cells, skin cells, blood vessel cells, eye cells) are the same size even in different animals. Small animals like bugs have the same size cells as larger animals like elephants or whales or birds.
Bacteria though, and other single celled organisms, have cells much smaller than animal cells. In fact, more bacteria cells are present in the human body than animal cells! So, the cells of single-celled organisms are much smaller than those of multi-celled organisms. In animals, small and large have about the same size cells.
No, unicellular means one cell but multicellular means multiple (more than one) cells.
multi celled organisms are bigger than single celled
why they are.
It takes less cells to do the job. If you cut yourself, then your body can send less cells to heal the wound compared to when the cells are smaller. You need more cells when you are smaller then when you have the larger cells.
Adding more cells
Cells have a correct size, they do not grow bigger or smaller. Growth hormone causes the development of new cells. You get more cells, rather than bigger cells.
It all depends... Cells vary from size to size. The largest cell is an ostrich egg which is larger than most tissues, however tissues are made from cells working together to achieve a common purpose. If it is a multicelled organism than the cells will be smaller than it's own tissues.
No, chromosomes are smaller than cells. Chromosomes are found in the nucleus of cells which codes for the synthesis of proteins.

myccorhizae.
All cells are smaller than human(except when you're comparing a chicken egg to an embryo)
the smaller prokaryotic cells would provide a scource of energy to the larger cells
The difference is that a unicellular organism has one cell and has a shorter life, is much smaller, and has a larger amount of predators. A multicellular organism has a larger size meaning less predators and larger animals, longer life because unlike unicellular organism who just die after losing its only cell a multicellular organism stays alive, and a big difference is multicellular organism have specialized cells like heart muscle cells, and brain cells.
It Is Larger!!
Larger

Girrafe is an eukaryotic organism while bacteria is procaryotic. As we know that eukaryotic organism has larger cells than prokaryotic organism so girrafe has larger cells than a bacterium.
No, they are larger.
The number of cells gets larger, and the organism gets bigger
